Core 2--- Week of February 13-17

Monday, 2/13
Toolkit Entry - Quadratic Formula  (This powerpoint walks you through what we did, but not necessarily how we did it...)
Practice Using only Positive Values of a, b and c.
Homework #6 - Monday's Problems Only


Tuesday, 2/14
Today we went over common mistakes that are made while calculating the roots using the quadratic formula and then tried a few problems with multiple negative values...  These common errors include...

• When b is negative, you must put parenthesis around b² (on your calculator)
• When b is negative, don’t forget that  –b (as in:  –b/2a) will be positive.
• When dividing be sure to multiply the denominator of the fraction (2a) before you divide.
• Be sure to take the square root before you divide.    

Homework #6 - do Tuesday's problems tonight.
